var mDialog = Dialog(mActivity)
mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
mDialog.window.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))

mDialogBinding.btnClose.setOnClickListener {v ->

mDialog.setContentView(mDialogBinding.root)

mDialog.setCancelable(true)

fun getDisplayMetrics() {
    val displayMetrics = DisplayMetrics()
    windowManager.defaultDisplay.getMetrics(displayMetrics)
    
    return displayMetrics
}

3.1.2. Get DIsplay Pixels

fun getWidthPixels() {
    var displayMetrics = getDisplayMetrics()
    val displayWidth = displayMetrics.widthPixels
    return displayWidth
}

fun getWidthPixels() {
    var displayMetrics = getDisplayMetrics()
    val displayWidth = displayMetrics.heightPixels
    return displayWidth
}

3.1.3. Get Dialog Window Size

fun getWindowAttributes(mDialog: Dialog) {
    return mDialog.window!!.attributes

fun getWindowWidth(mDialog: Dialog) {

params.height = getWindowHeight(mDialog)
mDialog.window!!.attributes = params

3.2.2 Use Layout Parameter

var params = getWindowAttributes(mDialog)
params.width = WindowManager.LayoutParams.WRAP_CONTENT
params.height = WindowManager.LayoutParams.MATCH_PARENT
mDialog.window!!.attributes = params
